Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: Its ultra-low 0.56pF capacitance and ±0.05pF tolerance enable precise tuning of LC tank circuits in narrowband filters and VCOs, reducing signal attenuation.
• High-Speed Digital Decoupling: The C0G/NP0 dielectric offers negligible voltage and temperature coefficient, ensuring stable decoupling for PLLs and clock generators operating at 50V transients.
• Sensor Interface Circuits: In capacitive sensing front-ends, the 0402 miniature footprint and ±0.05pF accuracy allow compact layout with repeatable stray capacitance, improving measurement linearity.

Key Features & Advantages

• Ultra-Stable C0G/NP0 Dielectric: Maintains ±0.5% capacitance change over -55°C to +125°C, delivering consistent performance in temperature-sensitive analog circuits.
• Extreme Tolerance Precision: ±0.05pF ensures design repeatability for RF filters and timing networks, reducing production tuning steps.
• Space-Saving 0402 Package: Occupies minimal board area while handling 50V, making it ideal for miniaturized IoT modules and multi-layer PCBs.

Frequently Asked Questions

1. Q: What makes GJM1555C1HR56WB01D different from a standard 0402 MLCC?
   A: Its 0.56pF capacitance is at the extreme low end of the value range, combined with a ±0.05pF precision tolerance and Murata’s GJM series low-loss construction, optimized for VHF/UHF applications where conventional capacitors introduce too much resonance.
2. Q: Is GJM1555C1HR56WB01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free, meeting EU directive 2011/65/EU.
3. Q: What is the MOQ? Can we get small batches?
   A: We support small batch orders and fast BOM kitting assistance at SZYY, including prototyping quantities for this low-capacitance value.
