GRM21BR61H106KE43L is a Murata GRM-series multilayer ceramic capacitor (MLCC) rated 10uF, 50V DC, ±10% tolerance, X5R Class II dielectric, and 0805/2012 metric body measuring 2.0mm x 1.25mm with maximum thickness about 1.45mm, supplied tape-and-reel for automated SMT . It operates from -55°C to +85°C, uses nickel-barrier tin-plated terminations, is non-polar, RoHS/REACH compliant, and targets mobile-device, consumer, and general-purpose power-filtering applications where high capacitance density, small footprint, and 50V headroom are required.
Engineers should note X5R capacitance is voltage- and temperature-dependent: nominal 10uF degrades under DC bias and within the X5R ±15% over temperature band, so final value must be checked with vendor DC-bias curves and applied only where stable timing or precision reference capacitors are not critical.
FAQ
Q: Is it X5R or X7R?
A: Distribution lists X5R for GRM21BR61H106KE43L; if -55°C to +125°C or tighter high-temp stability is required, select an X7R/XP7R 0805 alternative and revalidate bias/footprint.
Q: How much capacitance remains under bias?
A: X5R loses capacitance as DC voltage rises; check Murata SimSurfing or datasheet curves at the target rail, then design with worst-case effective uF, not nominal 10uF.
Q: Can it replace electrolytic bulk caps?
A: It handles high-frequency decoupling well, but for high ripple-energy bulk storage pair it with low-ESR polymer/aluminum or use multiple MLCCs to meet ESR/capacitance margins.
