KWX Chip Resistors CHS

Product catalog summary

Overview: This document provides technical specifications and application details for CHS High Value Thick Film Chip Resistors manufactured by Shenzhen KWX Electronics Co., Ltd. It includes information on features, applications, dimensions, ordering information, performance, and ratings.

Features:

High value chip resistors in thick film.
Low temperature and voltage dependency.
Contact areas made of PtAg for gluing and soldering.
Untrimmed for higher voltage applications up to 6000V.

Applications:

Analyzing instruments and meters.
Computers, telecom, and wireless devices.
Military electronic equipment.
Medical electronic applications, such as X-Ray machines and high voltage devices.

Dimensions: The document provides detailed dimensions for various power ratings, ranging from 50mW to 1500mW, with specific measurements for length (L), width (B), thickness (D), and width of wraparound (C).

Ordering Information: The CHS series resistors are available in different styles (0402, 0603, 0805, 1206, 1210, 2512, 4020) with power ratings from 50mW to 250mW. Resistance tolerance options include ±0.5%, ±1%, ±5%, ±10%, and ±20%. Temperature Coefficient of Resistance (TCR) values range from ±25ppm/℃ to ±3000ppm/℃.

Performance: The resistors are tested according to JIS C 5201-1 standards. Key performance parameters include:

Temperature range: -55℃ to 125℃.
Climatic category: 55/155/56.
Solderability: 235℃ for 2 seconds, max soldering temperature of 260℃ for 10 seconds.
Long-term stability under storage at 125℃ for 1000 hours and max voltage for 1000 hours.

Applications and Ratings: The document details power ratings, working voltage, resistance range, tolerances, TCR, and Voltage Coefficient of Resistance (VCR) for different resistor types. It includes specific values for trimmed and untrimmed resistors, with varying tolerances and TCR values.

Derating Curve: A derating curve is provided to illustrate the relationship between ambient temperature and rated power, indicating that power decreases as temperature increases beyond 70℃.
