MCM01-009DD270J-TF is a multilayer mica RF capacitor designed for high-power, high-frequency applications requiring low inductance and reliable performance at elevated temperatures. This surface-mount component features a capacitance of 270 pF with ±5% tolerance (J-code), rated for 500 Vdc operation, and utilizes mica dielectric material for superior stability and performance. The device operates across a temperature range up to 200°C and exhibits excellent ESR and impedance characteristics across the RF spectrum, as demonstrated in typical performance data for similar MCM01-009 configurations. The MCM01-009 style is particularly suited for RF circuits, high-current applications, and systems requiring low-loss energy storage in compact form factors, with dimensions approximately 0.460" × 0.365" × 0.110" to 0.165" depending on capacitance value.
