Description
Trimmer capacitors are variable capacitors which serve the purpose of initial calibration of equipment during manufacturing or servicing. Trimmer capacitors are used to initially set oscillator frequency values, latencies, rise and fall times for antennas, RF Equipment, Medical Equipment and other variables in a circuit. Should the values drift over time, these trimmer capacitors allow adjustment to re-calibrate equipment when needed.

Different Types for different purposes:

  • 6 different Diameters [mm]: 5.0; 6.0; 7.5; 9.5; 16.0; SMD
  • 5 different dielectric materials: PI Polyimide, PP Polypropylene, PC Polycarbonate, PTFE Polytetrafluorethylene, CC Ceramic in standard and Hi-temperature range
  • Voltage range: 150-300VDC
  • Capacitance range: 0.8pF-430pF

Specifications
The foil-trimming-capacitors are in accordance with DIN IEC 60418-1 and 4 - former DIN 44261 part 3.

The testing methods for sampling and data evaluation are in accordance with MIL-STD-105D and IEC60410 (former DIN 44260). The solder ability and resistance to heat of the foil-trimmer-capacitors comply with DIN IEC 60418-1 clause 23 - Test Ta and Tb.

Life of trimmer capacitor: Maximum 10 cycles with rotation in 180deg only (the electrical performance is not guaranteed if rotated more than 10 cycles).

Each capacitor is tested for minimum and maximum capacitance value and is also subjected to the full test voltage. If no technical conditions of delivery have been negotiated the components will be delivered according to AQL (0,15 for major defect  and 0,65 for minor defects).

Packing will be done bulk packed in card board boxes with plastic trays inside.
