MLCC GJM1555C1H5R0BB01D

What is GJM1555C1H5R0BB01D MLCC?

The GJM1555C1H5R0BB01D is a precision multilayer ceramic capacitor manufactured by Murata. Key specs include 5 pF capacitance, 50 VDC rating, C0G/NP0 dielectric, and a tight ±0.1 pF tolerance in a 0402 package. RoHS compliant, it is designed for high-frequency stability and low-loss signal path applications.

✔ RoHS Compliant  /  ✔ 0402  /  ✔ Murata Quality  /  ✔ Long-Term Supply

Typical Applications & Why This Part Fits

• RF impedance matching networks: The 5 pF value with ±0.1 pF tolerance provides the precise capacitive reactance needed for 50 Ω matching in Bluetooth and Wi-Fi front-end modules.
• VCO (voltage-controlled oscillator) tank circuits: C0G/NP0 dielectric ensures negligible capacitance drift over temperature (-55°C to +125°C), stabilizing oscillation frequency in wireless transceivers.
• High-speed digital DC-blocking: 50 V rating offers reliable isolation on I/O lines, while the 0402 footprint minimizes parasitic inductance in densely packed PCB layouts.

Key Features & Advantages

• Ultra-tight tolerance (±0.1 pF): Eliminates the need for tuning or trimming in sensitive analog and RF circuits, reducing calibration overhead.
• C0G/NP0 temperature coefficient: ±30 ppm/°C near-zero drift maintains stable filter cutoff frequencies across the full operating temperature range.
• 50 VDC rated voltage: Handles moderate bias conditions in IoT modules and battery-powered devices without derating concerns.

Frequently Asked Questions

1. Q: What makes GJM1555C1H5R0BB01D different from a standard 0402 5 pF MLCC?
   A: Unlike general-purpose X7R or X5R parts, this Murata GJM series offers C0G/NP0 stability and ±0.1 pF tolerance, making it suitable for precision RF and timing circuits where capacitance variation must be minimal.
2. Q: Is GJM1555C1H5R0BB01D RoHS compliant?
   A: Yes, as a Murata product, it is standardly RoHS compliant and lead-free.
3. 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 and small-batch flexibility for design verification.
