21.4 mhz crystal filter 6pads/4pads
This 21.4 MHz crystal filter is a precision RF component designed for narrowband communication applications. The filter operates at a center frequency of 21.4 MHz with a passband of ±7.5 kHz measured at the 3dB cutoff points, providing selective filtering for intermediate frequency stages in communications equipment. The package style is 7x5 mm with either 4-pad or 6-pad configurations, and the filter delivers a stopband attenuation of ±25.0 kHz at 35 dB rejection, effectively suppressing out-of-band signals.
The filter features a 6-pole design with a ripple specification of 1.0 dB across the passband and maximum insertion loss of 2.5 dB. The terminating impedance is specified as 1500 Ohms in parallel with 0.5 pF, with a coupling capacitance of 5 pF between filter sections. These specifications make this filter suitable for high-selectivity IF filtering in HF and VHF receivers, test equipment, and frequency synthesizers where narrowband performance is critical.
This type of crystal filter is typically purchased by electronics manufacturers building communication transceivers, radar systems, and test instrumentation. The product is sourced as a catalog item with standard specifications suitable for most commercial and industrial RF applications. Importers should verify termination impedance matching and confirm the pad configuration (4-pad versus 6-pad) matches their PCB layout requirements.

Sourcing 21.4 MHz Crystal Filter from Chengdu Xtalong Electronics - China Import Guide
Before placing an order for this 21.4 MHz crystal filter, verify the exact pad configuration (4-pad vs 6-pad) matches your PCB layout and mounting requirements. Request the manufacturer's data sheet to confirm all electrical specifications, particularly the S21 passband shape and group delay characteristics. Confirm whether the 1500 Ω // 0.5 pF termination requirement is compatible with your existing circuit design or requires matching components. Ask the supplier for batch-to-batch consistency data and whether each unit is 100% tested or sampled.
Logistics and payment terms should be confirmed directly with Chengdu Xtalong Electronics as these are not stated in the listing. Typical lead time for crystal filters ranges from 2-6 weeks depending on order quantity and current production schedule. Incoterms (such as FOB, CIF, or EXW) and payment methods (T/T, L/C, or PayPal for small orders) must be negotiated. Shipping via express courier is common for sample orders, while sea freight is economical for larger production quantities. Confirm whether the supplier provides individual unit packaging or reel packaging for automated assembly.
Quality verification should include requesting a test report with measured S-parameters for each lot, confirming insertion loss, passband ripple, and stopband attenuation meet specifications. For production orders, consider arranging pre-shipment inspection through a third-party inspection service. Documentation typically includes commercial invoice, packing list, and certificate of origin. If your application requires regulatory compliance (such as RoHS or REACH), request confirmation and relevant documentation from the supplier to ensure the components meet your market's chemical restrictions.
