Procurement Notes

Verify current availability directly with Microchip Technology or authorized distributors as this component may be subject to special order status. Confirm specific package style requirements and terminal finish options before placing orders. Ensure compliance with RoHS directives and handle components using appropriate ESD precautions during storage and assembly processes.

Selection Notes

Select the GC1502-00 when a 1.2 pF nominal capacitance is required for VHF through Ku Band tuning applications. Consider the 30V breakdown rating and operating temperature range for environmental suitability. Evaluate the Q factor and capacitance ratio specifications against circuit requirements for optimal filter or oscillator performance.
