• Features an optimized internal electrode design enabling low-profile module integration.
• Delivers equal or superior insertion loss and attenuation performance relative to previous generations.

Applications

• RF circuitry in smartphones
• RF circuitry in tablets
• LTE system integration

Procurement Notes

Verify the specific datasheet version and mechanical dimensions against your PCB layout requirements before finalizing procurement. Confirm that the operating temperature range of -40 to +85℃ aligns with your environmental specifications. Ensure compatibility with your manufacturing processes for 0202 (0505 Metric) package components. Cross-reference official TDK documentation for any updates to electrical characteristics or material compliance status.

Selection Notes

Select this component when space constraints are critical, as it offers a 50 percent size reduction compared to standard IEC1005 filters. Consider its use in applications requiring low-profile designs due to the 0.3mm insertion height. Evaluate its performance for LTE and next-generation wireless systems where superior attenuation is necessary. Ensure the -40 to +85℃ operating range meets your thermal requirements.
