The Product Lineup of PTC Thermistor of Murata Production Institute Is Expanded

Murata Manufacturing Co., Ltd. expanded the product lineup of PTC thermistors for overcurrent protection of smart phones and small wearable devices, and increased the size of 0603m (0.6 × zero point three × 0.3mm) high voltage withstand product "prg03bc181rb7rl" and low resistance product "prg03bc101rb7rl". These two products have begun mass production.

PTC thermistor is commonly known as self recovery fuse (PTC is the abbreviation of positive temperature coefficient thermistor). In case of overcurrent due to incorrect connection or short circuit in the circuit, the self recovery fuse will blow to protect the circuit; After the overcurrent disappears, it will automatically return to the original state and can be reused. The purpose of PTC thermistor is to protect the circuit from overcurrent by detecting the overcurrent of electronic circuit when the temperature rises and the resistance value rises sharply after reaching a certain temperature.

Resistance temperature characteristic curve of this product

With the continuous advancement of high functionality and miniaturization caused by the support of 5g and fast charging by mobile devices such as smart phones, there is an increasing demand for small circuit protection components to ensure the stability of electronic circuits. Because PTC thermistor has the characteristic that the resistance value rises sharply when it exceeds a certain temperature, it can prevent abnormalities and faults of mobile equipment by detecting the circuit overcurrent generated by mobile equipment during assembly or falling.

Through the process technology cultivated in the company's main products such as monolithic ceramic capacitors and multilayer equipment, compared with the company's traditional products (resistance value 180 Ω, maximum voltage 13V), when the size is the same, the withstand voltage is increased by about 50% to 20V. In addition, the company has expanded the lineup of 100 Ω low resistance product series. By using the unique ceramic materials of the company, the stable characteristics can be maintained for a long time.

Advantages of this product

In the future, the company will continue to expand its product lineup to meet market demand and contribute to improving the security of mobile devices.

Rechargeable Battery.The 100% Biba brand new environmentally friendly rechargeable battery has inherited the powerful genetic advantages of GP Speedmaster. Compared with the traditional Ni-MH rechargeable battery, the new 100% Biba environmentally friendly rechargeable battery has a 1.2V full-range constant voltage and a large capacity of 2300mAH. The revolutionary technology makes it a new-generation leader in the rechargeable battery industry. Under the recommendation of gamers, 100% of the new Buba battery was snapped up by the whole people, and battery sales continued to soar, and it was also known as "the best cp partner for Xbox controllers."The discharge performance of the new generation of 100% Biba environmentally friendly rechargeable batteries is quite strong, suitable for use in various high-current and high-voltage electronic devices such as gamepads and wireless mice. The social media 3DM game network has conducted actual evaluation on it, and the results show that the 100% Biba battery does have excellent performance. Faced with the tests of many games such as "Monster Hunter WorldIn the 5-hour gaming experience, the fully-powered 100% Biba battery strongly assists the Xbox controller, presenting an excellent gaming feast full of speed and excitement.In addition to the amazing battery life, the new generation of 100% Biba's new generation of environmentally friendly rechargeable batteries has also passed the authority SGS quality certification. More than 90% of its battery materials can be recycled, and the battery can be used repeatedly for more than 300 times. The environmental protection level is among the top in the world. . Even if it is stored for one year in the standby state, the battery still has more than 70% of the remaining capacity. Excellent quality can naturally be loved by consumers.In terms of charging safety, 100% must be very careful. Under the concept of striving for perfection, 100% Beba fits the life charging scene, and designed a "back window" hollow charger with automatic power-off intelligent recognition, so that the safety issues such as heat dissipation, short circuit, overcharge, etc. have been greatly improved. The improvement brings us a safer charging environment.It can be said that the emergence of a new generation of environmentally friendly rechargeable batteries with 100% Biba has become a boon for game enthusiasts. I believe this 2300 mAh super-capacity rechargeable battery set combination, you will fall in love with it after using it!fqj
