MCR10EZPF1052 Visão geral
A thick-film chip resistor is a passive component in which a metal-glaze resistive paste is screen-printed onto a ceramic alumina substrate and fired at high temperature, then trimmed to the target value with a laser or abrasive cut. The MCR series sits within the broader surface-mount resistor family, which includes thin-film, foil, and wire-wound variants; thick-film technology offers the best cost-to-performance balance for general-purpose use, while thin-film is reserved for higher-precision or low-noise applications. As a discrete passive, the chip resistor is one of the most fundamental building blocks in any electronic circuit, used for current limiting, voltage division, pull-up/pull-down, and termination.
Key features of the MCR10EZPF1052 include a 10.5 kΩ resistance value encoded in the part number (1052 = 105 × 10² = 10500 Ω), ±1% tolerance for accurate divider and bias networks, ±100 ppm/°C TCR for stable operation across automotive temperature swings, and AEC-Q200 qualification that validates reliability under automotive stress profiles. The 0805 footprint measures 2.0 × 1.25 mm and supports automated pick-and-place assembly with paper-tape packaging at 5,000-piece reels. Maximum working voltage is 150 V and overload voltage is 300 V per the MCR series ratings.
Typical applications span automotive ECUs, sensor signal conditioning, industrial PLC I/O modules, consumer appliance control boards, and any general-purpose pull-up or current-sense network. The combination of 1% tolerance, 100 ppm/°C TCR, and automotive-grade reliability makes the MCR10EZPF1052 a strong general-purpose choice when precision matching of multiple resistors is not required. Where tighter ratio tolerance is needed (e.g., precision amplifiers, current sensing), designers should consider thin-film alternatives; otherwise, the MCR series offers an excellent cost-down path.

Aplicações típicas
MCR10EZPF1052 é adequado para 6 aplicaçãos: Automotive ECU Signal Conditioning, Industrial PLC Input Divider, Consumer Appliance Control Board, Battery Management I-sense Bias, Sensor Module Pull-Up Network, Power Supply Feedback Network.
Automotive ECU Signal Conditioning
The MCR10EZPF1052's 10.5 kΩ ±1% tolerance and AEC-Q200 qualification make it well suited for analog signal-conditioning networks inside automotive ECUs, where it commonly serves as a pull-up for open-drain sensor outputs (e.g., Hall-effect, temperature sensors) or as the upper leg of a resistive voltage divider scaling a 0–5 V sensor signal into a 0–3.3 V ADC input range. The ±100 ppm/°C TCR keeps the divider ratio stable across -40°C to +125°C under-hood thermal swings, while the 0.125 W rating provides ample margin for typical sub-mW signal-chain dissipation. Compared with thin-film alternatives, the MCR thick-film construction offers a strong cost-down path for high-volume ECU production without sacrificing automotive reliability.

Industrial PLC Input Divider
In industrial PLC discrete-input modules, the MCR10EZPF1052 functions as the high-side resistor in a 24 V-to-5 V resistive divider that scales field-wiring voltages down to logic levels for the PLC's input multiplexer. The 10.5 kΩ value pairs with a 2.2 kΩ low-side resistor to yield a 1.8 V logic-low threshold with adequate noise margin, while the 0.125 W power rating handles the divider's continuous dissipation (≈50 mW) with a 2.5× safety margin. The wide -55°C to +155°C operating range covers outdoor control cabinets and factory-floor installations. AEC-Q200 qualification, while designed for automotive, also satisfies industrial reliability expectations for shock, vibration, and temperature cycling.
Recomendado
Consumer Appliance Control Board
The MCR10EZPF1052 is widely deployed in consumer appliance control boards (washing machines, microwave ovens, dishwashers) for low-current biasing of microcontroller I/O, button-matrix pull-ups, and LED indicator current limiting. Its 10.5 kΩ value provides a typical 1–3 mA bias current at 3.3 V or 5 V logic levels, well within the 0.125 W continuous rating. Surface-mount 0805 packaging enables automated pick-and-place on high-volume appliance lines, and the thick-film construction delivers the cost-per-piece required for consumer price points. The ±1% tolerance is more than sufficient for non-precision biasing roles where exact resistance values are not critical to circuit function.
Recomendado
Battery Management I-sense Bias
In low-side battery current-sense amplifiers for single-cell Li-ion packs, the MCR10EZPF1052 serves as the input bias resistor for the sense-amp's reference node or as a filter resistor on the battery-monitor IC's analog supply pin. The 10.5 kΩ value, combined with a 0.1 µF decoupling capacitor, creates a 150 µs RC time constant that filters high-frequency switching noise from the upstream DC-DC converter. The part's ±100 ppm/°C TCR keeps the bias network stable as the battery pack warms during high-current discharge, and the 0.125 W rating easily handles the sub-microwatt dissipation in this biasing role.
Recomendado
Sensor Module Pull-Up Network
For I²C-bus or SPI-bus sensor modules (accelerometers, gyroscopes, pressure sensors, environmental sensors), the MCR10EZPF1052 provides the I²C SDA/SCL pull-up to VCC, sized at 10.5 kΩ to balance rise-time against current consumption at standard 100 kHz and 400 kHz bus speeds. In SPI-mode sensor modules, the same value works as a CS (chip-select) pull-up to keep the line high during MCU reset. The 0805 footprint fits the compact sensor-module PCBs common in IoT and wearable designs, and the thick-film construction handles the brief charge/discharge currents of bus signaling within its 0.125 W rating with substantial margin.
Recomendado
Power Supply Feedback Network
In non-isolated buck or boost converter feedback networks, the MCR10EZPF1052 functions as the upper feedback resistor in the resistor-divider that scales the output voltage down to the converter's internal reference (typically 0.6 V to 1.2 V). The 10.5 kΩ value sets the divider ratio in conjunction with a lower resistor to program a 3.3 V or 5 V output. The ±1% tolerance holds the output voltage within ±1% of nominal under steady-state conditions, and the ±100 ppm/°C TCR keeps the regulated output stable across the converter's operating temperature range. The 150 V maximum working voltage provides ample margin for 12 V and 24 V input rails.

Principais diferenciais
- AEC-Q200 automotive qualification standard across the MCR10EZPF series (vs RC0805FR-0710K5L (Yageo))
- Wide -55°C to +155°C operating temperature range with zero-power derating point (vs ERJ-6ENF1052V (Panasonic))
- Long-running MCR series with established automotive reliability track record (vs CRCW080510K5FKEA (Vishay))
Notas de projeto
The MCR10EZPF1052 is rated at 0.125 W at 70°C ambient and must be derated linearly to zero power at 155°C. Estimated: in a typical voltage-divider with 24 V across the resistor string, dissipation is roughly 24² / (10.5k + 2.2k) ≈ 45 mW, well within rating. For high-voltage divider strings above 100 V, verify the 150 V working-voltage limit is not exceeded and add pulse-withstanding consideration for transients.
Use IPC-7351 nominal land-pattern pads of approximately 1.30 × 1.05 mm for the 0805 footprint. Reflow profile should follow JEDEC J-STD-020 with peak temperature ≤260°C for lead-free assembly. For high-humidity or automotive under-hood environments, ensure the PCB solder-mask and via-in-pad design prevent flux entrapment under the part, which can cause tombstoning during reflow.
Do not assume MCR10EZPF-series parts with different suffix codes are interchangeable: the 4-digit suffix encodes resistance, and 1052 (10.5kΩ), 1002 (10kΩ), and 1003 (100kΩ) look similar but have very different electrical behavior. Always confirm the resistance value from the part-number suffix or reel label. For ±1% tolerance parts, the actual resistance can vary by up to ±105 Ω from nominal, which matters in precision divider or current-sense networks.
