Frequently Asked Questions
What resistance and power rating does the ERJP14F4302U offer, and what tolerance class is it?
The ERJP14F4302U provides 43kΩ resistance with ±1% tolerance (F suffix) and a 0.5W power rating. Its ±100ppm/°C temperature coefficient ensures stable resistance from -55°C to +155°C, making it appropriate for precision voltage divider networks and instrumentation circuits where resistance drift over temperature must be minimized.
For a 43kΩ voltage divider from a 5V rail, what output voltage and current does ERJP14F4302U produce with a 10kΩ lower leg?
In a voltage divider with a 43kΩ upper resistor (ERJP14F4302U) and a 10kΩ lower resistor from a 5V rail, the output voltage equals 5V × 10k/(43k+10k) ≈ 0.94V, with a divider current of approximately 94µA. The 0.5W power rating of the 43kΩ resistor is well within limits at this current level, making this configuration suitable for ADC reference scaling in microcontroller-based systems.
How does the 1210 package size of ERJP14F4302U compare to 0805 for this resistance value?
At 43kΩ, heat dissipation is minimal at typical signal voltages, but the 1210 package (3.2mm × 1.6mm × 0.6mm) provides a 0.5W power rating versus 0.25W for an equivalent 0805 resistor. The larger footprint offers greater soldering robustness and easier visual inspection during PCB assembly, which benefits high-reliability production environments even when the power advantage is not the primary selection criterion.
Is ERJP14F4302U interchangeable with resistors from other manufacturers in the same 1210 case?
The ERJP14F4302U follows the standard 1210 SMD package dimensions (3.2mm × 1.6mm × 0.6mm) and uses compatible land patterns, so it is dimensionally interchangeable with 1210 resistors from other manufacturers at the same 43kΩ ±1% rating. Engineers should verify the replacement part's power rating meets 0.5W, temperature coefficient matches ±100ppm/°C requirements, and that it carries equivalent RoHS and REACH compliance documentation.
What procurement considerations apply to ordering ERJP14F4302U in volume?
The ERJP14F4302U carries a factory lead time of 22 weeks from Panasonic, which requires advance planning for production builds. With a 12-year YTEOL rating, the part remains in active production for long-lifecycle designs. Volume buyers should establish blanket orders with authorized distributors or negotiate safety stock agreements to buffer the 22-week lead time and avoid supply chain delays on high-volume PCB assembly schedules.
