## Description

The TE Connectivity 2-1904058-5 is a specialized high-voltage automotive relay engineered from the Mini K HV Series, optimized for DC precharge architectures in hybrid electric vehicles (HEV), full battery electric vehicles (BEV), and fuel-cell automobiles. Built to manage high-potential circuits, this electromechanical relay features a 12 VDC nominal coil voltage with a 50-ohm coil resistance, drawing a rated coil power of 2.9 W. Its single-pole, single-throw, normally open, double-make (SPST-NO DM / 1 form X) contact configuration utilizes a durable silver alloy material system capable of handling continuous precharge and limiting break currents up to 20 A at a nominal contact voltage of 400 VDC (with maximum switching voltages reaching 450 VDC and 9 kW switching power). 

Designed for robust through-hole PCB mounting, the component incorporates solder terminals and offers a dielectric strength of 2800 VDC between open contacts and between the contact and coil. It delivers rapid switching performance characterized by a typical operate time of 2.5 ms and a release time of 1 ms, alongside a low initial contact voltage drop of typically 150 mV at 10 A. The relay operates reliably within an ambient temperature range of -40°C to +85°C and withstands severe environmental stressors, including damp heat, thermal shock cycling, and wide-band mechanical vibrations in accordance with IEC standards. Strict adherence to layout guidelines regarding internal pin isolation, alongside maintaining minimum creepage and clearance distances, ensures safe integration within high-density automotive power distribution systems.

- 1) Consult TE Connectivity for insulation compatibility with higher voltages. 

- 2) Load circuit: L/R <14µs. 

- 3) After 10 fault break operations relay must be replaced. 

- 4) Test conditions: on-time 100ms, off-time 10s. 

- 5) Valid for recommended 250Ω suppression resistor (PCB version). Note: A low resistive suppression device in parallel to the relay coil increases the release time and reduces the lifetime due to increased erosion and / or higher risk of contact tack welding.

## MAX. im 

**Notes regarding PCB-layout and terminal assignment:** 

- Pin 4 must not be electrically connected, no solder eye at that pin is allowed, only a drill-hole without via 

- Potential assignment of pins: 

- pins 1; 2: low voltage (LV) 

- pins 5; 7; 4(*): high voltage (HV) 

- pin 8a; 8b: no potential but internally connected 

- (*) pin 4 is on HV potential in ON-state of relay only. 

## **Notes regarding clearance and creepage distances:** 

- The required clearance and creepage distances between HV and LV potential must be ensured. 

- Layout of the PCB has to ensure min. clearance and creepage distances of conducting relay parts and relay terminal 1 and conducting relay parts and terminal 2 respectively. Refer to detail drawing. 

Minimum distance to neighboring ferruginous parts: 3mm.
