Resistor Networks, Arrays

YC158TJR-0720RL is an integrated surface-mount device that contains two 8-pin resistors and two single resistors. It is divided into two parts: the first one is a basic 8-pin resistor, which is a thin-film resistance element with a resistance of 40Ω. The second part is two single resistors, one with a resistance of 30Ω and the other with a resistance of 0.5Ω. The YC158TJR-0720RL can be used in several application areas for circuit protection.

Application Field

YC158TJR-0720RL is typically used in the consumer electronics and automotive industries. It is used to protect power systems from electric shocks, voltage surges, and other destructive phenomena. In consumer electronics, YC158TJR-0720RL provides an effective solution for voltage protection to prolong the life of the components in the electronic device. It is usually used in AC and DC power supplies and systems, DVDs, chargers, IT equipment, and other electrical equipment. In automotive electronics, it is used to protect the battery, power supply, and ECU from damage due to voltage spikes or load fluctuations. YC158TJR-0720RL is also widely used in LED lighting to provide surge protection for sensitive loads.

Working Principle

YC158TJR-0720RL works by allowing excess current to flow through the resistor instead of damaging the electronic device. The built-in resistors act as a load that limits the amount of current flowing through the circuit, preventing it from exceeding the device’s maximum current rating. It also helps prevent voltage spikes in the circuit. When the voltage rises above a certain level, the resistor will act as an ‘over-current protection’ device, dissipating the excess energy to protect the device.

When the voltage reaches a certain level, usually more than two volts, the resistor will start to conduct more current, shielding the device from further voltage rises. This regulation is especially important in automotive applications, where voltage spikes generated by the engine can be very destructive to the electronics.
