HV733ATTE226J 概要
A thick-film chip resistor is a passive component in which a resistive ruthenium-oxide (or equivalent) film is screen-printed onto a ceramic alumina substrate, laser-trimmed to the target value, and covered with a protective glass overcoat. Within the broader component taxonomy, this device sits at: chip resistor -> fixed resistor -> resistor -> passive component -> electronic component. The high-voltage HV73 family is positioned for circuits where conventional 2512 resistors fail due to arcing, creepage, or insufficient working-voltage derating.
Key specifications include 22 MΩ nominal resistance, ±5% tolerance, ±200 ppm/°C temperature coefficient (TCR), 1 W rated power at 70 °C, 3000 V maximum working voltage, and a moisture-resistant thick-film construction rated for -55 °C to +155 °C operation. The 2512 land pattern is the same JEDEC footprint used by every standard 2512 chip resistor, enabling drop-in PCB layout compatibility with other 2512 parts.
Technically, the HV73 series uses a widened internal resistive-element pattern and a specialized terminal geometry to extend creepage and clearance distances across the top of the chip, which is what enables the 3 kV working-voltage rating. The 200 ppm/°C TCR is typical of thick-film ruthenium-oxide systems and is acceptable for non-precision high-voltage bias roles where absolute ohmic accuracy is secondary to voltage withstand.
Typical applications include high-voltage dividers in medical imaging and X-ray equipment, bleeder resistors on capacitor banks in industrial power supplies, voltage sensing in EV traction inverters and on-board chargers, high-side sensing in photovoltaic (solar) inverters, and insulation-test (hipot) instrument input networks. It is also commonly used in CRT/LCD manufacturing equipment and electrostatic precipitator control boards.
When designing with the HV733ATTE226J, observe derating: KOA specifies 1 W at 70 °C ambient with linear derating to 0 W at 155 °C. Maintain at least 0.5 mm of solder-resist-free creepage around the terminations and avoid placing low-voltage signal traces beneath the resistor body.

主な用途
HV733ATTE226J の用途: 6 件s: High-Voltage Divider / Bleeder Networks, Medical Imaging & X-Ray Equipment HV Bias, Photovoltaic Inverter High-Side Sensing, EV Traction Inverter & On-Board Charger HV Sensing, Hipot / Insulation Tester Input Networks, Industrial Electrostatic Precipitator (ESP) Control Boards.
High-Voltage Divider / Bleeder Networks
The HV733ATTE226J is well-suited to high-voltage divider and bleeder resistor positions in industrial power supplies, capacitor-bank discharge circuits, and test-instrument front-ends. Its 22 MΩ value pairs naturally with low-value precision thin-film resistors (e.g., 100 kΩ) to build divide-by-200 or divide-by-1000 networks for safely sensing kilovolt rails. The 3 kV working-voltage rating, 1 W dissipation, and moisture-resistant thick-film construction ensure long-term reliability under sustained high-voltage stress. Compared to general-purpose 2512 resistors rated at only 200-500 V, the HV73 family eliminates arc-over risk on the bench and in the field, and the 200 ppm/°C TCR is acceptable for sensing rather than precision-measurement roles.

Medical Imaging & X-Ray Equipment HV Bias
In medical imaging equipment such as dental X-ray heads, portable radiography units, and CT scanner bias supplies, the HV733ATTE226J provides reliable high-voltage bias and grid-leak resistance. The 3 kV working-voltage rating comfortably covers the 30-80 kVp bias rails found in dental X-ray tubes when used in series-resistor stacks, and the 1 W power rating handles the steady-state dissipation under continuous operation. The moisture-resistant thick-film construction withstands the humidified sterilization environments typical of clinical use, while the 2512 footprint enables compact PCB layouts in space-constrained X-ray generator modules. Designers must still observe minimum creepage and clearance per IEC 60601-1 and apply a 50% voltage derating for patient-connected equipment.

Photovoltaic Inverter High-Side Sensing
Solar photovoltaic (PV) inverters require high-impedance voltage-sensing networks on the 600-1500 V DC string side to feed isolated ADC inputs and MPPT controllers. The HV733ATTE226J's 22 MΩ value, 3 kV working-voltage rating, and 1 W rating make it ideal for HV-side sensing resistor strings where standard 2512 parts would fail prematurely due to arcing. The 2512 SMD format supports automated assembly on the inverter control board, and the moisture-resistant thick-film element tolerates the humid under-glass environment of outdoor PV installations. The ±5% tolerance and ±200 ppm/°C TCR are adequate for MPPT control loops where the controller calibrates out offset and gain error at startup.
おすすめ
EV Traction Inverter & On-Board Charger HV Sensing
Electric-vehicle traction inverters and on-board chargers (OBCs) operate at 400 V or 800 V DC bus voltages and require robust high-impedance sensing networks tied to isolated gate drivers and BMS front-ends. The HV733ATTE226J fits as the high-side element of 800 V bus voltage dividers, providing the 22 MΩ value and 3 kV working-voltage headroom needed for safe sensing well above the maximum bus rail. The 1 W rating supports continuous sensing without overheating, and the 2512 footprint simplifies integration onto densely populated OBC PCBs. AEC-Q200 qualification of the underlying KOA HV73 family supports automotive-grade designs, and the moisture-resistant construction survives under-hood thermal cycling per AEC-Q100 stress profiles.
おすすめ
Hipot / Insulation Tester Input Networks
Production-line hipot testers and insulation-resistance meters generate high test voltages (typically 500 V to 5 kV) and measure microamp-level leakage currents through high-impedance sense networks. The HV733ATTE226J serves as the input current-limiting and range-setting resistor in such instruments, where its 22 MΩ value establishes the measurement range and its 3 kV rating matches common test voltages. The 1 W dissipation rating is more than sufficient for the microamp-level leakage currents measured, and the ±5% tolerance is acceptable given that production testers typically self-calibrate against an internal reference. The 2512 SMD format supports compact handheld-instrument PCB layouts.
おすすめ
Industrial Electrostatic Precipitator (ESP) Control Boards
Electrostatic precipitators used in industrial air-pollution control and dust-collection systems operate at 30-100 kV DC and require high-impedance bleeder and sense networks on the high-voltage side. The HV733ATTE226J is used in series-resistor strings to divide down the sensing voltage for isolated ADC input, where the 3 kV per-resistor rating allows 30+ resistors to be stacked for 100 kV strings. The 1 W power rating and thick-film construction provide long-term reliability under continuous high-voltage stress, and the 2512 footprint supports automated assembly of the long series-resistor chains. The moisture-resistant construction is critical in dusty, humid industrial environments where general-purpose resistors would fail prematurely.

設計ノート
The HV733ATTE226J is rated at 1 W continuous power at 70 °C ambient, with linear derating to 0 W at 155 °C per the KOA HV73 datasheet derating curve. Estimated: at 110 °C ambient (typical industrial enclosure interior), the resistor can only dissipate approximately 0.45 W. Always apply a 30-50% safety margin and confirm the application's worst-case ambient before committing the part to a high-density design.
Maintain at least 0.5 mm of solder-resist-free creepage distance around the terminations and avoid placing low-voltage signal traces beneath the resistor body. The KOA HV73 series achieves its 3 kV rating through extended creepage across the top of the chip, which can be compromised by solder-resist slivers or flux residue under the part. For series-resistor strings on >10 kV rails, provide at least 8 mm of clearance between adjacent resistors to prevent surface arcing.
Do not substitute a generic 22 MΩ 2512 resistor (typical 200-500 V working voltage) for the HV733ATTE226J in high-voltage applications - it will arc and fail. Always verify the working-voltage spec on the substitute datasheet matches or exceeds the application's maximum bus voltage. Also note that the ±200 ppm/°C TCR makes this part unsuitable for precision measurement roles; use thin-film resistors where <50 ppm/°C is required.
At 22 MΩ and 3 kV, the resistor continuously dissipates approximately (3000 V)^2 / 22,000,000 Ω = 0.41 W in steady state - well within the 1 W rating, but in series-resistor strings the dissipation sums. For a 10-resistor 30 kV divider, total dissipation is roughly 4 W distributed across 10 chips (0.41 W each), leaving thermal headroom for transient surges. Always calculate worst-case DC dissipation and add margin for AC ripple and surge events.
