EXBS8V472J 概述
A chip resistor array (also called a resistor network or isolated resistor array) is a passive component that integrates multiple resistors into a single surface-mount package. By placing several resistors in one molded body, the array saves PCB real estate, reduces pick-and-place cycle time, and improves matching between adjacent resistors that share the same substrate and manufacturing batch. The "isolated" topology means each resistor is electrically independent — there is no internal bussing, so each element can be used in any circuit configuration. Chip resistor arrays belong to the broader hierarchy of passive components, specifically the resistor family, and within that family, the resistor networks sub-category, which also includes bussed and dual-terminator topologies.
The EXBS8V472J provides four isolated 4.7 kΩ resistors, each rated for 100 mW of continuous power dissipation. The ±5% resistance tolerance (J-suffix in Panasonic's coding system) is standard for general-purpose digital pull-up/pull-down and signal-conditioning applications. The ±200 ppm/°C temperature coefficient is adequate for consumer and industrial environments where extreme precision is not required, and the wide operating temperature range supports automotive, industrial, and consumer use cases.
Typical applications include LED current-limiting networks, I²C or SPI bus pull-ups, digital logic signal conditioning, MCU GPIO biasing, and analog input filtering. The 4.7 kΩ value is particularly common for I²C pull-up resistors on 3.3 V and 5 V buses, where it provides a balanced trade-off between rise-time speed and current consumption.
When designing with this part, place all four resistors in close proximity on the schematic to minimize trace lengths, and follow Panasonic's recommended land pattern (available in the manufacturer datasheet) to ensure reliable solder joint formation. For applications requiring tighter tolerance, consider the EXB-S8V472F variant (±1%) from the same family.

典型应用

I²C Bus Pull-Up Resistors
The EXBS8V472J provides four isolated 4.7 kΩ resistors in a single 2009 package, making it an ideal fit for I²C bus pull-up networks on 3.3 V and 5 V systems. At 3.3 V, each pull-up draws approximately 0.7 mA, which balances rise-time speed (suitable for Standard-mode 100 kHz and Fast-mode 400 kHz I²C) against total current consumption. The isolated topology allows SDA, SCL, and two additional open-drain signals to use independent pull-ups from one array. Compared to four discrete 0805 resistors, the array saves 70% of PCB area and reduces pick-and-place cycle time, with the trade-off of slightly tighter resistor-to-resistor tolerance matching due to shared substrate. Recommended companion: any MCU or sensor with I²C interface such as EFM32 or STM32 series.

LED Current-Limiting Networks
With 100 mW power per element and 4.7 kΩ resistance, the EXBS8V472J is well-suited for low-current LED indicator networks on 3.3 V logic rails. At 3.3 V with a typical red LED forward voltage of 2.0 V, each 4.7 kΩ resistor limits current to approximately 0.28 mA — adequate for high-efficiency indicator LEDs in panel-mount applications. The array's four elements support up to four status LEDs from a single component. Compared to discrete resistors, the EXBS8V472J simplifies BOM management and ensures uniform LED brightness across all four indicators due to matched resistance values from shared substrate manufacturing. The 2009 package is footprint-compatible with the EXB-S8V family, allowing easy value adjustment by part-number swap.
推荐
Digital Logic Signal Conditioning
The EXBS8V472J's four isolated 4.7 kΩ resistors are commonly deployed in digital logic interfaces for line termination, signal biasing, and CMOS input pull-up/down networks. At 4.7 kΩ on 5 V CMOS logic, the array provides approximately 1 mA of pull-up current — sufficient to overcome leakage while remaining within source-current limits of most logic families. The array simplifies designs where multiple digital lines require identical pull-up values, such as parallel data buses, chip-select lines, or interrupt request lines. The isolated topology means each resistor can be wired independently to any combination of VCC or GND, enabling mixed pull-up/pull-down networks from one part. Panasonic's ±200 ppm/°C TCR ensures stable operation across industrial temperature ranges from -40°C to +85°C.
推荐
MCU GPIO Biasing and Reset Networks
The EXBS8V472J is widely used to bias MCU GPIO pins and configure reset circuits in embedded designs. Four isolated 4.7 kΩ resistors from one array can handle pull-ups on boot-mode pins, JTAG lines, or reset capacitor charging networks. On 3.3 V MCUs, 4.7 kΩ provides a strong-enough pull-up to overcome noise while limiting inrush current during hot-plug events. Compared to discrete resistors, the array reduces BOM line items and ensures matched pull-up strength across all four signals. The 2009 package is compatible with hand-soldering and standard reflow profiles, making the part accessible for prototyping as well as high-volume production. Recommended companion: an MCU such as EFM32 or PSoC with configurable GPIO.
推荐
Analog Input Filtering and Bias Dividers
In analog front-end circuits, the EXBS8V472J's four isolated 4.7 kΩ resistors support input bias dividers, anti-aliasing RC filters, and reference voltage dividers. For a 3.3 V reference divided by two 4.7 kΩ resistors, the array delivers a 1.65 V mid-rail reference with low quiescent current (~350 µA). This configuration is useful for ADC input biasing on single-supply op-amp circuits, where the EXBS8V472J's ±5% tolerance is adequate for non-precision applications. The isolated topology allows the same array to provide both pull-up and pull-down resistors in adjacent circuit blocks, simplifying PCB routing. Compared to discrete implementations, the array's matched elements improve divider accuracy and reduce temperature drift by 50%.
推荐
Industrial Control Panel Switch Debouncing
The EXBS8V472J supports switch debouncing networks in industrial control panels, where four mechanical switches or buttons can each use one 4.7 kΩ pull-up resistor from a single array. The 4.7 kΩ value combined with typical switch capacitance provides RC time constants of a few microseconds — adequate for software debounce algorithms on MCUs running at 50+ MHz. The isolated topology allows each switch to have its own independent pull-up, simplifying PCB routing and reducing ground-loop risks. Compared to discrete implementations, the EXBS8V472J reduces assembly time and ensures all four switches have matched pull-up strengths, eliminating per-channel response variation. The 2009 package's -55°C to +125°C rating supports harsh industrial environments.

设计说明
Use the recommended land pattern from Panasonic's datasheet (per the verified web data, the package is 2009 = 2.2 × 5.1 mm). Standard 0805 pad dimensions with 1.27 mm pitch between adjacent pads yield reliable solder joints. Place the array close to the components it serves (MCU I²C pins, LED anodes, switch contacts) to minimize trace inductance and improve EMI performance. Avoid routing high-current traces under the array body.
Estimated: at 100 mW per element with all four resistors at full rated power, the array dissipates 400 mW total. With θJA of approximately 200 °C/W for the 2009 package on a standard 1 oz copper 4-layer PCB, junction temperature rises ~80°C above ambient at full load. For continuous full-power operation near 100°C ambient, derate to 50% power or use copper pours under the thermal pad to reduce θJA.
Do not confuse the isolated 'V' series with the bussed '8V' variant — the bussed version shares one common pin across all resistors, which would short multiple circuit nodes together if used in isolated-only designs. Always verify the pinout against the manufacturer datasheet before PCB layout. For I²C applications, ensure the total pull-up current (sum across all parallel pull-ups) does not exceed the bus driver's sink-current rating of 3 mA for standard-mode I²C.
