What is GJM1555C1H4R5WB01D MLCC?
The GJM1555C1H4R5WB01D is an SMD capacitor manufactured by Murata（村田）. Key specs include 4.5pF capacitance, 50V voltage rating, C0G/NP0 dielectric, and ±0.05pF tolerance. RoHS compliant, it is designed for high-frequency precision and stable filtering.
✔ RoHS Compliant / ✔ 0402 / ✔ Murata（村田） Quality / ✔ Long-Term Supply
Typical Applications & Why This Part Fits
- RF Matching Circuits: The tight ±0.05pF tolerance and C0G/NP0 temperature stability ensure consistent impedance matching in wireless modules operating at 50V.
- Timing & Oscillator Networks: With 4.5pF nominal value and minimal drift, this MLCC provides reliable frequency determination in 0402 footprint oscillators.
- Filtering in Portable Devices: The 50V rating combined with 4.5pF allows adequate decoupling for low-power RF stages while keeping the 0402 size on dense PCBs.
Key Features & Advantages
- Ultra-Tight Tolerance: ±0.05pF enables precision tuning without additional trimming, critical for narrow-band RF applications.
- C0G/NP0 Dielectric: Offers near-zero capacitance change over temperature and voltage, ensuring stable performance across -55°C to +125°C.
- Murata Production Consistency: High reliability with low ESR at high frequencies, ideal for 0402 space-constrained designs.
Frequently Asked Questions
- Q: What makes GJM1555C1H4R5WB01D different from a standard 4.5pF MLCC?
A: Its ±0.05pF tight tolerance (vs typical ±0.25pF) and Murata’s GJM series optimize for RF/ microwave performance, reducing insertion loss variation. - Q: Is GJM1555C1H4R5WB01D RoHS compliant?
A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free. - Q: What is the MOQ? Can we get small batches?
A: We support small batch orders and full BOM kitting at SZYY, including fast prototyping supply.
