THINKING, One Step Forward Toward Auto Industry
2013-05-06
 
 
 
 
ISO/TS 16949 is an international quality management system for automotive industry. THINKING’s factory located in Kaohsiung, Taiwan, is certified by ISO/TS 16949 in 2005. Then, those in Dongguan and Changzhou, China, are verified in 2006. Finally, the one in Yichang, China, receives the certification in late 2012.

THINKING Converts to IECQ QC 080000:2012 Certificate
2013-04-19

 
 
 
 
IECQ QC 080000 is an internationally recognized HSPM (Hazardous Substance Process Management) system, and its new standard is released on June 1, 2012. THINKING passes the conversion audit of QC080000:2012 and obtains the certificate in April, 2013.
 
THINKING originally implements QC080000:2005, which is the old standard and only mentions RoHS. However, QC080000:2012, the new standard, covers more legislation, including RoHS2, REACH, and China RoHS. Both RoHS and RoHS2 prohibit the use of six substances (Pb, Cd, Hg, PBB, PBDE, and Cr6+ ). RoHS2, the latest standard, adds HBCDD, DEHP, DBP, and BBP as controlled substances. HBCDD is used as flame retardant, and the rest are as plasticizers. Those substances endanger human health and the environment.
 
When implementing QC080000:2005, THINKING controls the four substances mentioned above. It also controls raw materials and production process to protect employees and users against potential health risks and reduce pollution in the environment. That indicates THINKING uses stricter standard than legislation to manufacture its products.
 
THINKING shows its management ability of green product while obtaining QC 080000:2005 certificate in 2009. This conversion to QC 080000:2012 further indicates its improvement in green product management. In other words, THINKING adapts the latest HSPM system to make “THINKING Inside” customer products follow global green trend.

THINKING Recommended by Teridian 73M2901CE
2010-05-28

Teridian Semiconductor, a US-based semiconductor company that designs and develops analog and mixed-signal ICs, listing THINKING polymer PTC resettable fuse as recommended components in demo board user manual of its IC design product, 73M2901CE.
 
73M2901CE is a single chip low speed modem that includes all the modem functions, and its programmable configuration options make it highly adaptable to a variety of applications, including satellite set-top box, point-of-sale terminal, automatic teller machine, remote monitoring device, metering device, vending machines, and smart card reader.
 
Over-current protection is required for a reliable design that will survive in the severe conditions occurred by short circuit or voltage cross to power mains. Fuses as over-current protection components prevent the design from failing caused by those conditions. Comparing with one-time fuse, resettable fuse is able to reset itself after short circuit and does not need to have replacement fuses. Therefore, in 73M2901CE demo board user manual, KRT600 (600 V, 150mA) and KRT250 (250 V, 120mA) of KRT series are recommended components for over-current protection. This UL, cUL, and TUV recognized series passes 6kV test and is compliant with UL60950 and EN-60950, meeting Teridian customers’ needs of isolation voltage and agency approvals.

THINKING Introduces New Thermally Protected Varistor - TVT Series
2009-09-16

Continuous over-voltage, which is mostly caused by the line imbalance of neutral to ground in AC line or abnormal connection of power system, triggers a varistor into a continuous clamping condition and results in fire or smoke. Therefore, THINKING launches new thermally protected varistor, TVT series, to effectively disconnect the varistor from circuit under abnormal over-voltage and limited current condition (requirement of UL 1449 3rd Edition, Section 39.4) to ensure user safety. 

Thanks to TVT’s patented design, the components offer faster disconnection time and more reliable operation to replace thermal fuse in circuit, so that reduces part count. In addition, thermal fuse is not suitable for wave soldering. TVT’s excellent heat resistance solves this problem and enables automatic production. In other words, TVT series is a good solution for over-voltage protection and cost control. 

Those components are available in a body size of 14 mm, 20 mm, 22 mm, 25 mm, and 34 mm (diameter), with an operating voltage ranged from 130 Vac to 750 Vac, and a withstanding current capability raged from 6000 A to 40000 A. TVT series is recommended over-voltage protection components of power supply, Uninterruptible Power Supply, TVSS module, lightning surge protection products. The most popular 14 mm and 20 mm products are TUV approved.
