Demand for high precision and low TCR is rapidly increasing across automotive, industrial, and data server applications.
The ERJPC Series delivers thin-film-level precision within a robust thick-film chip resistor design. It combines excellent accuracy with enhanced environmental resistance and superior power handling—effectively addressing multiple performance challenges in a single solution.
Key Features
The ERJPC Series achieves resistance tolerance (±0.1%) and temperature coefficient of resistance (±25 ppm/K) equivalent to thin-film resistors, while maintaining thick-film construction through proprietary materials and process design.
High Precision
Tight resistance tolerance of ±0.1% and low TCR of ±25 ppm/K deliver high-precision performance.
High Power Rating
Provides up to 2× higher power rating than thin-film resistors of the same size.
High Reliability
Offers excellent resistance stability with ΔR within ±0.2% and inherent environmental robustness.
Pb-free Construction
Manufactured using lead-free materials for environmentally responsible construction.
Compliance
Fully compliant with AEC-Q200 and RoHS standards.

Comparison with Conventional Thin Film Resistors
Compared with thin film resistors of the same size, the new high precision thick film resistors (ERJPC) provide higher power capability, allowing the same power rating to be achieved in a smaller case size. ERJPC series enables up to 50% PCB space saving, supporting overall board miniaturization.
