SMD Ceramic Trimmer Capacitors for Precision RF and Tuning Circuits

Overview

The TSC3S series SMD ceramic trimmer capacitor is designed for fine capacitance adjustment in high frequency and resonant circuits.
Its miniature form factor and stable electrical performance make it suitable for automated assembly and precision tuning applications.

Key Features

• Compact dimensions: 3.2 (W) × 4.5 (L) × 1.5 (T) mm
• Designed for reflow soldering processes
• Low capacitance drift during adjustment
• High Q factor and high resonant frequency
• Color-coded case for identification
• Sealed construction to prevent flux and dust ingress

Electrical Function in Circuits

Ceramic trimmer capacitors provide adjustable capacitance for frequency alignment and impedance tuning.
High Q and low loss characteristics support stable oscillation and narrow-band filtering in RF signal paths.

Applications

• RF tuning networks
• Oscillator frequency adjustment
• Impedance matching circuits
• Communication equipment calibration
• High frequency signal processing modules

Design Considerations

• Place within accessible tuning area for post-assembly adjustment
• Ensure reflow profile compatibility with PCB process
• Consider Q factor requirements for resonant circuits
• Avoid mechanical stress during adjustment to maintain stability
