CERAMIC CHIP MIL-PRF-123

Category: Capacitors, Electronics, Kemet Electronics Corporation

Overview

This datasheet provides detailed information on KEMET’s CERAMIC CHIP capacitors which adhere to the MIL-PRF-123 specification. These capacitors feature solder-coated and solder-plated terminations with a composition of 60Sn/40Pb or 70Sn/30Pb. The available size options range from the compact 0805 package to the larger 2225.

Capacitor Dimensions and Marking

All capacitors are laser marked with the KEMET trademark and a two-digit capacitance symbol, ensuring easy identification. The document includes a chart detailing military chip designations alongside KEMET’s own designations, dimensions for each size category (such as length, width, and thickness), and the maximum number of terminations in various configurations.

For solder coated terminations, additional tolerances are specified to the positive width, thickness, and length tolerances. Important is the inclusion of the dimensions in inches with military style codes assigned to each capacitor size variant.

Ordering Information

Detailed ordering information is covered outlining how to specify the termination type, failure rate, temperature characteristic, size, capacitance, tolerance, working voltage, and any modification numbers relevant to the MIL-PRF-123 specification. Selection can be made from various termination types including nickel guarded solder-coated or 70/30 tin/lead plated. The failure rate is standard and not applicable for these capacitors.

Capacitance and Tolerance

Capacitance is denoted via a picofarad code where the first two digits indicate the significant figures, and the third digit conveys the number of zeros that follow. Tolerance options range from ±0.25pF to ±10%, allowing designers to choose capacitors that best suit their precision requirements.

Working Voltage and Temperature

These capacitors are designed for a working voltage of 50V or 100V and a temperature range of -55°C to +125°C. Temperature characteristics are detailed with the corresponding changes in capacitance with temperature, classified under ‘Ultra Stable’ and ‘Stable’ conditions based on the capacitance change with temperature measured without and with DC bias voltage.

Military Specifications and Styles

The datasheet lists the military specification number MIL-PRF-123 where each part is identified with a unique KEMET Style, closely mapped to a MIL-PRF-123 slash sheet number. This ensures compliance with military standards and allows users to easily cross-reference with the MIL-PRF-123 specification sheet.
