What is TZB4P400AB10R00 used for?
The TZB4P400AB10R00 is used in RF oscillator circuits, VCO (voltage-controlled oscillator) tuning networks, and antenna matching networks where precise capacitance adjustment between 8.5 pF and 40 pF is required. Its 100 V rating makes it suitable for RF transmitter output stages and high-voltage tuning loops in amateur radio and professional communication equipment. The vertical adjuster allows field calibration of resonant frequency after final PCB assembly.

Frequently Asked Questions
What is the tunable capacitance range of the TZB4P400AB10R00 trimmer capacitor?
The TZB4P400AB10R00 tunes from a minimum of 8.5 pF to a maximum of 40 pF, giving a 4.7:1 capacitance ratio across its adjustment range. This wide range is useful for aligning LC oscillators and resonant filters across broad frequency bands. In an RF circuit with a 100 nH inductor, this 8.5 pF to 40 pF range shifts the resonant frequency between approximately 80 MHz and 170 MHz.
Why is the 100 V voltage rating of TZB4P400AB10R00 important for RF tuning applications?
In RF oscillator and transmitter circuits, AC voltage swing across a tank capacitor can reach several tens of volts peak depending on output power level. The 100 V rating of the TZB4P400AB10R00 provides substantial margin above typical RF swings in low-to-medium power transmitters operating at 1 W to 5 W, preventing dielectric breakdown or nonlinear behavior that would degrade frequency stability and harmonic distortion.
How does the vertical adjuster orientation of TZB4P400AB10R00 affect PCB assembly and field calibration?
The vertical adjuster places the trimming screw on the top face of the 3 mm tall component. This allows a standard flathead or crosshead trimmer tool to access the adjustment after the PCB is fully assembled and installed in an enclosure with a top access hole. Field technicians can align the oscillator frequency without desoldering or removing the board, which is especially valuable in calibrated RF instruments and communication transceivers.
Can TZB4P400AB10R00 replace trimmer capacitors from other manufacturers in existing designs?
Replacement compatibility depends on matching the 8.5 pF to 40 pF range, 100 V rating, vertical adjuster style, and PCB footprint. Murata's TZB4P series uses a specific 3-pin footprint; competing trimmers from Bourns, Sprague-Goodman, or Voltronics may differ in pin pitch or body dimensions. Verify that the replacement trimmer fits the existing 3 mm height constraint and matches the footprint pad spacing before substituting in production.
