ISABELLENH Ü TTE (ISA) Brand Introduction
Company Overview
ISABELLENH Ü TTE was founded in 1482 and is headquartered in Germany. It is a leading global manufacturer specializing in precision alloy materials, low resistance resistors, and current sensors. Its history can be traced back to the field of metal smelting and processing, managed by the Hoysler family since 1827, with nearly 500 years of technological accumulation to date. The company focuses on materials science and precision manufacturing, with products covering resistors, sensors, thermoelectric materials, etc., widely used in high-precision fields such as automotive electronics, new energy, and industrial automation.
Core Technologies and Product Lines
Isa is known for its low resistance shunt resistor technology. In 1987, it launched the world's first surface mount milliohm level current sensing resistor, establishing a benchmark position in the industry. Its core technologies include:
ISAPLAN ®：
Using metal film etching/printing technology, manganese copper alloy (Manganin) ®） Low inductance and low thermal resistance resistance resistance electrodes made of materials are suitable for surface mount resistors (such as VMP series) and miniaturized precision detection scenarios.
ISAWELD ®：
By welding copper and alloy materials with high-energy electron beams, it supports flexible shape designs (such as four terminal structures) and is suitable for high current scenarios (such as electric vehicle battery management systems).
Core product series:
VMP series (patch splitter): resistance as low as 5m Ω, power of 3W, accuracy of ± 1%, temperature coefficient as low as 20ppm/℃, used in automotive electronics and industrial power management.
PBV series (aluminum shell precision resistor): 10W power, resistance range 4.7m Ω -150m Ω, accuracy ± 0.5%, suitable for high reliability scenarios.
Current sensor:
IVT series: Integrated CAN communication interface, supports dynamic current detection, used for electric vehicles and energy storage systems.
Technical advantages
Ultra low resistance and high precision: The resistance range covers 5 μ Ω to 100 Ω, with a tolerance as low as ± 0.1%, and long-term stability better than 0.3%.
Low temperature drift characteristics: Temperature coefficient (TCR) as low as 1ppm/℃, stable performance at extreme temperatures.
High power and pulse resistance: Some products have a continuous power of up to 500W and support high pulse loads (such as motor drives and fast charging systems).
Low parasitic inductance: Optimized structural design with parasitic inductance below 0.1nH to reduce high-frequency interference.
