Chip Inductors have 0.9 mm profile.

Press Release Summary:

Featuring 1A-class power rating, CKP3216 series of 1206 case size multilayer chip inductors are suited for dc-dc converter choke coil applications in portable electronic device power circuits. Series, offering current ratings from 0.7-1.1 A and 4.7-1.0 µH respectively, takes advantage of internal-electrode printing process, which results in dc resistance values from 0.20-0.11 Ω. Applications include multifunction cell phones, digital still cameras, and digital video cameras.

Taiyo Yuden Introduces Industry's Thinnest 1206 Chip Inductors

CKP3216 series offers 1A-class power rating & 0.9mm maximum height-ideal for DC-DC
converter choke coils in new generation of ultra-thin, multifunction electronic portables

SCHAUMBURG, IL-November 8, 2005-TAIYO YUDEN (U.S.A.), INC.'s new CKP3216 series of 1206 case size multilayer chip inductors offer the industry's lowest profile for DC-DC converter choke coil applications in portable electronic device power circuits. With a maximum height of 0.9mm, CKP3216 series devices provide a lower profile than typical surrounding ICs, thus facilitating the design of thinner, higher-performance, multifunction cell phones, digital still cameras, digital video cameras and other battery-powered ultra-portable electronic equipment. Offering current ratings from 0.7 to 1.1A and 4.7 to 1.0µH, respectively (see table), low-profile CKP3216 series chip inductors are now available in mass production quantities in the following part numbers:
Part Number  Inductance @ 1MHz     RDC        Current Ratings
(µH ±20%) (Ohms) (A)

CKP3216 1R0 1.0 0.11 1.1
CKP3216 1R5 1.5 0.13 1.0
CKP3216 2R2 2.2 0.14 0.9
CKP3216 3R3 3.3 0.16 0.8
CKP3216 4R7 4.7 0.20 0.7

Smaller, thinner, multifunction device technology continues to drive the battery-powered portable market, in which hard-disk drives, voice recorders, larger color LCD screens, and other advanced features now require smaller, thinner choke coils and multiple DC-DC converters. In response, TAIYO YUDEN developed the industry's lowest-profile 1206 inductors, the performance characteristics of which are the result of the company's advanced material science techniques and improved component structure.

A proprietary new internal-electrode printing process enabled TAIYO YUDEN to double the thickness of the internal conductor compared to the company's previous-generation devices, resulting in lower DC resistance (RDC). Another material science-derived improvement was the prevention of inductance drop during the application of high current, an essential requirement in ultra-portable applications. New additions to the CKP3216 series, now under development, are expected to result in further performance gains in 1206 case size.
