What are the key features of ERJ-2RKF1004X?
- 1 MΩ resistance with 1% tolerance and ±100 ppm/°C temperature coefficient for precision signal conditioning and voltage reference dividers
- 0402 (1.0 mm × 0.5 mm) chip package rated at 0.063 W enables high-density PCB placement in compact consumer and industrial designs
- RoHS-compliant thick-film construction with anti-sulfur performance provides long-term reliability in harsh and industrial operating environments
What is ERJ-2RKF1004X used for?
The ERJ-2RKF1004X is used in precision voltage dividers, bias networks, and current-sensing circuits within consumer electronics, medical devices, and industrial sensors where tight 1% resistance accuracy and low temperature drift are required. Its compact 0402 footprint and 1 MΩ resistance value suit high-impedance input protection and pull-up/pull-down networks in battery-powered IoT and wearable designs. The 0.063 W power rating supports typical low-current signal-level applications operating at voltages up to 50 V.

Frequently Asked Questions
What resistance value and tolerance does the ERJ-2RKF1004X provide for precision circuit designs?
The ERJ-2RKF1004X provides a resistance of 1 MΩ with a 1% tolerance (F-grade), meaning the actual resistance falls within ±10 kΩ of the nominal value. Combined with a temperature coefficient of ±100 ppm/°C, this resistor maintains less than 0.01% additional resistance drift over a 100°C operating range, making it suitable for precision voltage dividers and sensor bias networks.
What is the power rating of ERJ-2RKF1004X and how does that limit its application in high-voltage circuits?
The ERJ-2RKF1004X is rated at 0.063 W (63 mW), which limits the maximum continuous voltage across the 1 MΩ resistor to approximately 250 V based on power considerations, though the maximum rated working voltage is typically 50 V for the 0402 package size. For circuits operating above 50 V, a larger package such as 0603 or 0805 with higher rated voltage should be selected instead.
How does the 0402 package size of ERJ-2RKF1004X compare to 0603 alternatives in terms of PCB space savings?
The ERJ-2RKF1004X in 0402 occupies a PCB footprint of 1.0 mm × 0.5 mm, which is approximately 40% smaller in area than a 0603 resistor (1.6 mm × 0.8 mm). This size reduction allows more components per unit board area, enabling higher functional density in compact designs such as wearables, hearing aids, and mobile device PCBs where every 0.5 mm² matters.
