The V250LTX4 is a Varistor series made by Littelfuse. It is an electro-mechanical protection device. It is designed for transient and surge minimization of AC or DC critical circuits. It dissipates peak pulses of any magnitude and waveform, without performance degradation and is highly resistant to heat and abrasion. It is an ideal choice for protection of high-voltage applications such as motor control, AC and DC power supplies, home appliances, and automotive applications.The V250LTX4 series is UL certified and suitable for many industrial and medical end markets. It is available in a variety of package sizes and power ratings, ranging from 9.4KW to 120KW, making it a reliable solution for protecting your circuits.

The V250LTX4 series provides superior surge-dissipation performance and stability due to its special construction. The device is composed of a metal oxide core and two layers of fuses, which are superimposed on the core. The core is usually made of zinc or tin oxide and is bonded to metal contacts, which are then soldered to the printed circuit board or wire. The metal oxide core consists of a ceramic matrix with zinc and tin oxides. The top and bottom layers of fuses provide the connection to the printed circuit board or wire. The device is capable of dissipating up to 1200A of 8/20μs waveforms.

The V250LTX4 series utilizes a Zener-diode-like action for intended surge and transient protection. When the transient voltage is below the device’s breakdown voltage, it acts as a shunt path for the transient current. This shunts the dangerous short duration pulse away from the sensitive electronics, and into the V250LTX4, and then out of the device.

The V250LTX4 series has a wide operating temperature range of –40°C to 125°C, making it suitable for use in many applications. The device has a high energy capability and exceptional surge performance, making it ideal for use in a variety of AC and DC power systems. It is well-suited for use in high-temperature and harsh-environment applications, and is qualified to automotive standards. Its robust design and low component height allows it to fit perfectly into many applications.

The V250LTX4 series is an ideal choice for those looking for reliable and versatile surge protection for a variety of applications. It is suitable for use in AC and DC power systems and has a wide operating temperature range, making it ideal for high-temperature and harsh-environment applications. Its robust design and low component height make it perfect for applications with limited space. It offers superior protection from transient and surge events, and is UL certified, ensuring a reliable and safe product.
