TDK Corporation (TSE:6762) announces the X1 capacitors of the EPCOS B3291xH/J4 series for power line filtering of electromagnetic interferences (EMI) in demanding automotive and industrial applications with a rated AC voltage of up to 480 V. Applications that are exposed to harsh climatic conditions such as PV inverters and EV onboard chargers (OBCs) can benefit from the new X1 capacitors’ high resistance to high humidity environments. With the ability to continuously handle a DC voltage of 1000 V, this series is a dedicated solution for DC EMC of high-voltage EV platforms.

The X1 capacitors are THB-tested (temperature, humidity, bias) at +85 °C, 85% relative humidity for 1000 hours at 380 V (AC) and 1000 V (DC), and they can operate at temperatures up to +110 °C.

Featuring self-healing properties, the series covers capacitance values from 15 nF to 10.0 µF and boasts a compact design, with dimensions ranging from 18.0 x 10.5 x 5.0 mm to 57.5 x 57 x 45 mm, depending on the capacitance. Lead spacings vary between 15 mm and 52.5 mm, with the largest versions equipped with 4 pins for enhanced mechanical stability on the PCB. The series is certified according to ENEC, UL, and CSA standards.

TDK Corporation (TSE:6762) announces the launch of the EPCOS B3292xM3/N3 series of X2 EMI suppression capacitors. These new components are 20% smaller than previous models and meet Grade III Test B standards for temperature, humidity, and bias (THB). Their compact size and enhanced durability suit space-constrained, high-humidity environments, especially for "across-the-line" applications in automotive and industrial settings.

The capacitors offer lead spacings from 15 mm to 37.5 mm and dimensions ranging from 18.0 x 5.0 x 10.5 mm to 42.0 x 14.0 x 25.0 mm (L x W x H), with capacitance values from 0.1 µF to 4.7 µF. Designed for harsh environments and AEC-Q200 compliant, the B3292xM3/N3 series is commonly used in automotive on-board chargers (OBCs), as well as industrial systems such as uninterruptible power supplies (UPS) and hybrid inverters for energy storage systems (ESS).

To meet Grade III Test B standards, they are tested at +85 °C and 85% relative humidity and subjected to rated AC voltage stress for 1000 hours (with lead spacing of 22.5 mm or more) or 500 hours (with 15 mm lead spacing). The components are rated for an AC voltage of 305 V and can handle a maximum DC voltage of 630 V continuously. With an operating temperature range of -40 °C to +110 °C, and self-healing properties due to their metalized polypropylene (MKP) dielectric, the B3292xM3/N3 series offers long-term reliability.

With its compact size and advanced durability, the B3292xM3/N3 series offers a reliable, high-performance solution for EMI suppression, helping engineers save space and maintain reliability in demanding environments.

TDK Corporation announces the EPCOS B32377G, a new series of three-phase AC filter capacitors in delta connection filled with nonflammable nitrogen gas instead of the soft polyurethane resin used in the existing series. Read more.
