Thick Film Chip Resistor and Jumpers – MC Series Datasheet

Category: Electronics, RCD Components Inc, Resistors

Executive Summary

This datasheet contains detailed information on Thick Film Chip Resistors and ZC Series Zero-ohm Chip Jumpers by RCD Components Inc, offering an industry-leading range of resistors with values ranging from 0.12 ohms to 22 megaohms and power ratings from 50 milliwatts to 3 watts. Resistance tolerances vary from ±0.25% to ±5%, with temperature coefficients as low as 50 ppm. The resistors are designed using precision thick film technology, characterized by low inductance and high reliability, making them suitable for high-demand applications.

Product Features

The MC resistors feature a heavy solder plating with nickel barrier for improved solderability and extended shelf life. The datasheet highlights the availability of 0402, 0603, 0805, and 1206 sizes, which are well-stocked in both 1% and 5% tolerances. Additional sizes are also well-represented with various popular values.

Customization Options

The datasheet mentions several customization options that enhance the resistors’ adaptability to different applications:

Lead-free solder terminations: An eco-friendly option indicated by ‘W’.
User-trimmable chips: This ‘U’ option allows users to adjust the resistance value if necessary.
Increased pulse capability: Option ‘P’ offers higher tolerance to power surges.
Additional services such as Mil-spec screening, special markings, non-standard values, and high frequency designs are noted as specialities of RCD.

Performance and Standards

The components are noted for their ability to withstand significant stress, including thermal shock from -55°C to +125°C, high temperatures (up to 155°C for certain applications), resistance to solder heat, moisture, and a lifespan of up to 1000 hours of load life. Power derating is applicable above 70°C, and extended ranges are available for necessity.

Pulse Withstand Capability

The datasheet presents a Pulse Withstand Chart for increased pulse levels, providing guidelines on pulse duration and peak voltage levels. It suggests derating factors for improved performance and recommends seeking assistance from RCD for specific application guidance.

Ordering Information

Detailed ordering information is laid out, demonstrating how to specify the RCD type, chip size, resistance value, tolerance, packaging, and temperature coefficient through specific alphanumeric codes. Zero-ohm chip jumpers are indicated by leaving certain fields blank.
