【FMBf Decade Capacitance Box Product Introduction】
The FMBf Decade Capacitance Box is a precision instrument designed for electronic testing and measurement applications. Featuring a modular decade switching system, it enables flexible capacitance configuration from 0.1pF to 100μF with high repeatability. The unit incorporates metallized polypropylene film capacitors and a precision contact system, achieving stable performance across temperature variations while maintaining minimal dielectric absorption.
Engineered with an innovative non-inductive design, the product utilizes multi-layer shielding technology to reduce equivalent series resistance (ESR) to milliohm levels, effectively minimizing circuit loading effects. The ergonomic rotary switch mechanism combines with a clear digital readout window, allowing single-handed operation and instant parameter verification - particularly advantageous for laboratory environments requiring repetitive adjustments. The hermetically sealed construction with wide temperature compensation circuitry ensures ±0.5% basic accuracy within -10℃ to +50℃ operating range.
This capacitance box demonstrates exceptional versatility in electronic component characterization, filter network analysis, and RF impedance matching applications. Equipped with BNC/QMA hybrid connectors, it seamlessly interfaces with oscilloscopes, LCR meters, and network analyzers. The durable aluminum-magnesium chassis with anti-fingerprint coating provides both mechanical robustness and electromagnetic shielding. Specialized protective covers and conformal coating treatment enhance operational reliability in demanding environments, making it suitable for extended use in research institutions, manufacturing facilities, and educational laboratories.
