The B72660M0140K072 is a leaded varistor from EPCOS (TDK), specifically designed to protect electronic circuits from transient overvoltages, such as those caused by lightning strikes, inductive load switching, or electrostatic discharge (ESD). These varistors are voltage-dependent resistors that exhibit a high resistance under normal operating conditions, effectively isolating the protected circuit. However, when a transient voltage exceeds a predetermined threshold, the varistor's resistance rapidly decreases, diverting the surge current away from sensitive components.

Applications

• Power supplies
• Inverters
• Motor controls
• Lighting systems
• Telecommunication equipment

Features

• High surge current capability
• Fast response time
• Wide operating voltage range
• UL, CSA, and VDE approvals
• RoHS compliant

Benefits

• Effective protection against transient overvoltages, extending the lifespan of electronic equipment
• Improved system reliability by preventing damage from voltage spikes
• Compliance with industry safety standards
• Reduced maintenance costs due to fewer component failures
• Enhanced product safety and performance

Additional Details

The B72660M0140K072 varistor is characterized by its key parameters, including maximum continuous operating voltage, surge current rating, clamping voltage, and energy handling capability. Refer to the EPCOS (TDK) datasheet for precise specifications and application guidelines. These varistors are typically constructed using a sintered zinc oxide ceramic material with appropriate additives to achieve the desired electrical characteristics. They are available in various leaded packages for through-hole mounting, allowing for easy integration into circuit boards.
