It’s also a good time to check smoke detectors and the thermal resistance of your isolators (see story at right).

NVE’s 25-Year Anniversary
 
25 Years of Leadership
NVE is celebrating its 25-year anniversary in March.

The company was founded in March 1989 as Nonvolatile Electronics, Inc. by Dr. James M. Daughton, a spintronics pioneer. Its first product, a ground-breaking GMR sensor, was introduced in 1994.

NVE is planning to celebrate with the world’s largest birthday cake (the current record is 130,000 pounds)*, and a spectacular fireworks display in the company lobby.**

Some highlights of the past 25 years:
    •   Two EDN Hot 100 Product awards
An EE Product News Top 20 Product
A Forbes Top Small Public Company four times
•   An Electronic Business' 30 Best Small Electronics Company
Two Technology Fast 50 awards and a Fast 500 award
A Tekne Innovation Award
 
*It might be scaled back to a half-sheet cake from Supervalu.
**Fireworks may be canceled due to safety issues.
 
New Distributor Down Under
Active Components
 
G'day to our new mates in Australia and New Zealand. Active Components is now distributing NVE’s award-winning IsoLoop Isolator product line.

Active Components has a number of offices in Australia and New Zealand, and is considered the largest electronic component distributor in New Zealand.
 
Recent Exhibitions
 
Embedded World 2013
Billed as the number one event for the embedded community, Embedded World is underway in Nürnberg, Germany. Distributor HY LINE Power Components is showing IsoLoop isolators. Isolated Bus Transceivers are popular for embedded applications.
 
From the Application Desk
 
IsoLoop Isolators Have
Excellent Thermal Characteristics

 
A frequent question to our Isolator applications desk is what is the thermal resistance of our isolator packages.

Award-winning IsoLoop® Isolators have excellent thermal characteristics, enabling the parts to run at high speed and high ambient temperatures with minimum temperature rises. This provides wide operating margin and contributes to exceptional reliability.

Thermal-related terms and symbols are illustrated as follows:

Thermal Specifications for Popular IsoLoop Packages
(soldered to double-sided board; free air)
 
The junction-ambient thermal resistances for SOIC-8, narrow-body SOIC-16, and wide-body SOIC-16 packages are similar. This is because higher case-to-ambient thermal resistance in the smaller packages is offset by lower junction-case thermal resistances since they are thinner and have relatively large leadframe areas. This convenient coincidence allows one derating curve for three package types (MSOP packages have higher junction-ambient thermal resistances).
