Precision Resistor Network Component – Computer, Electronic and Optical Product Manufacturing

Component Specifications

Definition

A precision resistor network is an integrated assembly of multiple high-precision resistors in a single package, designed to provide accurate resistance ratios and stable performance in electronic circuits. In portable digital multimeters, it ensures precise voltage division, current measurement, and signal conditioning for reliable readings.

Working Principle

Operates by providing precise resistance values to divide input voltages, set reference levels, and condition signals. The network maintains tight tolerance and low temperature coefficient to ensure measurement accuracy across varying conditions.

Materials

Thin-film or thick-film resistive elements on ceramic substrates, with nickel-chromium or tantalum nitride materials, encapsulated in epoxy or ceramic packages with gold-plated terminals.

Technical Parameters

Package Type SIP, DIP, or surface-mount
Power Rating 0.1W to 0.25W per resistor
Resistance Tolerance ±0.1% to ±0.01%
Operating Temperature -55°C to +125°C
Temperature Coefficient ±25 ppm/°C to ±5 ppm/°C

Standards

ISO 9001, IEC 60115
