Frequently Asked Questions
What combination of tolerance and temperature coefficient does the ERJP14F3902U offer?
The ERJP14F3902U provides a 39kΩ resistance with a tight ±1% tolerance and a low ±100ppm/°C temperature coefficient. This combination ensures the resistance deviation remains within approximately ±39Ω over a 10°C temperature change, making it suitable for precision voltage dividers and gain-setting networks in instrumentation circuits.
How does the 1210 package size of the ERJP14F3902U compare to smaller 0805 resistors for power handling?
The 1210 package (3.2mm × 2.5mm) of the ERJP14F3902U provides a 0.5W power rating, which is double the 0.25W typically offered by 0805 resistors. This larger footprint and higher wattage make it appropriate for circuits where the resistor must dissipate more heat, such as current sense or high-voltage divider applications.
For a 39kΩ feedback resistor in an op-amp circuit, why choose the ERJP14F3902U over a standard ±5% part?
The ±1% tolerance of the ERJP14F3902U limits gain error in op-amp feedback networks to under 1%, compared to up to 5% with standard parts. Combined with a ±100ppm/°C temperature coefficient, the resistor value remains stable within 0.1% over a 10°C operating range, preserving amplifier gain accuracy in precision signal conditioning designs.
Is the ERJP14F3902U available with short lead times for production procurement?
The ERJP14F3902U has a factory lead time of approximately 22 weeks from Panasonic. For immediate production needs, it is advisable to check authorized distributor stock levels, as quantities are often available from stock for fast delivery globally without waiting for the factory lead time.
