HVB

Product catalog summary

Introduction
Shenzhen KHX Electronics Co., Ltd. offers a series of ceramic resistors designed for high voltage, power charging/discharging circuits, and surge energy applications. These resistors conform to RoHS directives and are lead-free. They are particularly suitable for medical defibrillators and offer customizable designs for specific applications.

Specifications
The ceramic resistors are made from clay, silicon dioxide, and porcelain cement, sintered under high temperature and voltage. They are safer than wire-wound and film resistors, avoiding wire disconnection and film breakage. They can handle high peak power ranging from 5KW to 30KW in a short time and perform well under high voltage and current conditions.

Features
The HVB series offers surface insulation options in palm red or green and provides more choices compared to the HVA series. They are used in various applications such as radar, motor drives, broadcast transmitters, X-ray machines, lasers, medical defibrillators, dynamic braking, soft-start/current-limit, snubber circuits, dummy loads, energy research, RF amplifiers, semiconductor processes, and power conditioning.

Performance and Standards
The resistors meet performance standards as per IEC60115-1 and JIS C5201-1. They are tested for resistance value at an ambient temperature of 25℃±2℃ with moisture at 65%. The resistors have a rated ambient temperature of +70℃ and an operating temperature range of -40℃ to +200℃. The rated voltage is determined by the power rating and resistance value or the maximum working voltage, whichever is lower.

Dimensions and Construction
The resistors come in various types (HVB1/2, HVB1, HVB2, etc.) with specific dimensions and weights. The construction includes a resistive body, inner electrode, electrode cap, lead wire, and coating.

Testing and Reliability
Test methods include resistance to pulse, soldering heat, rapid temperature change, moisture resistance, load life, high-temperature exposure, and resistance to solvents. Performance requirements specify limits for resistance change under various conditions.
