MYH684K300H28 is a Y2 line-to-ground EMI/RFI suppression capacitor designed for harsh environmental conditions and automotive applications. The device features a capacitance of 0.68 µF with ±10% tolerance, rated for 300 VAC operation, and is housed in an H28 case package with dimensions of 32 mm length, 33 mm height, and 18 mm thickness. It exceeds industry standards with a 2,000-hour THB (thermal humidity bias) rating at 85°C and 85% RH, twice the standard 1,000-hour requirement, and is AEC-Q200 qualified for automotive-grade reliability. The capacitor operates across a wide temperature range from -40°C to +110°C with a dv/dt rating of 400 V/µs, and features a dissipation factor of 0.0020 at 1 kHz. This product is ideal for automotive EMI filtering, power supply decoupling, and line-to-ground noise suppression in demanding environments where durability and performance consistency are critical.
