Newsletter-Autumn 2023 | Thin Film Resistor Manufacturer | FIRSTOHM

In the face of climate change and environmental concerns, everyone can contribute to sustainable development by adopting energy-saving and emission-reducing practices. Initiating change from the minor routines of everyday life, such as turning off lights when not in use and minimizing unnecessary water consumption, represents steps that we can easily take. Firstohm's new factory is approaching its final stages of construction, featuring a specially integrated solar power generation technology on its roof. Simultaneously, energy consumption is being reduced through strategic production processes, thereby mitigating adverse environmental impacts. Significantly, Firstohm's MELF resistors are widely used in fields such as smart meters, solar inverters, electric vehicles, energy storage equipment, and more. These applications not only achieve energy-saving and emission-reduction goals but also serve as a key means to mitigate the impacts of climate change. FIRSTOHM is a high performance MELF resistors, SMD resistors, metal film resistors, surge resistors, wire wound resistors, precision resistors, High voltage resistors, high Power resistors, metal oxide resistor, thin film resistors, fixed resistors manufacturer from Taiwan since 1969.

Case study

★ Why are MELF resistors used in PV inverters?
PV inverters are critical energy conversion devices designed to convert the unstable direct current (DC) voltage generated by solar panels into a stable alternating current (AC) at grid frequency. This highly efficient inverter enables a bidirectional flow of electricity, allowing excess energy to be fed back into the commercial power grid or provided to off-grid electrical systems.
Due to the superior long-term operational stability and surge capability of MELF resistors compared to R-chip, they are widely used in the following circuits to demonstrate their advantages:
1. IGBT Gate Resistor - With exceptional voltage withstand capability, MELF resistors are suitable for IGBT gate control, ensuring efficient and reliable operation.
2. Filters - MELF resistors have lower inductance, effectively promoting efficient filtering effects, and contributing to signal stability.
3. Voltage/Current Sensing Circuits - MELF resistors offer precise current measurement, ensuring circuit accuracy and reliability.
4. Protection Circuits - MELF resistors are crucial in ensuring safe equipment operation and extended lifespan, maintaining system stability and reliability.
