MLCC GJM1555C1HR68WB01D

What is GJM1555C1HR68WB01D MLCC?

The GJM1555C1HR68WB01D is a high‑precision multilayer ceramic capacitor manufactured by Murata. Key specs include a capacitance of 0.68pF, a voltage rating of 50V, a C0G/NP0 temperature coefficient, and an extremely tight tolerance of ±0.05pF. RoHS compliant, it is designed for RF and high‑frequency circuits where stability and low loss are critical.

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

Typical Applications & Why This Part Fits

• RF Tuning & Impedance Matching: The ±0.05pF tolerance ensures near‑perfect resonance in LC tanks and antenna matching networks, while the C0G/NP0 dielectric offers negligible voltage and temperature drift.
• High‑Speed Signal Filtering: In 50Ω transmission lines, 0.68pF provides consistent capacitive loading for harmonic filtering without inserting excessive phase shift, supported by Murata’s tight manufacturing control.
• Sensor & Oscillator Circuits: The 0402 footprint saves board space in portable devices, and the 50V rating gives headroom for battery‑powered sensor front‑ends without risk of breakdown.

Key Features & Advantages

• Ultra‑Tight Tolerance (±0.05pF): Enables low‑variation circuit performance, reducing the need for manual tuning in production and improving first‑pass yield.
• High Stability C0G/NP0: Capacitance changes less than ±30ppm/°C, making it ideal for temperature‑critical oscillators and filter designs.
• Compact 0402 Form Factor: Occupies minimal PCB area, allowing dense placement in compact RF modules, wearables, and IoT end‑nodes.
