AVX expands inter-digitated capacitor product offering to include ultra-miniature, RoHS-compliant version
AVX has expanded its inter-digitated capacitor (IDC) product line to include ultra-miniature, RoHS-compliant versions. Providing low ESL values of 35pH in a small footprint, the IDC Series is ideal for advanced decoupling applications including CPU, GPU, ASIC and ASSP. Low ESL IDCs free up valuable board space by reducing the number of capacitors required versus standard MLCCs. In addition, IDCs reduce in the number of capacitors required in a design, thus lowering placement costs.
The key physical characteristic to determining the equivalent series inductance (ESL) of a capacitor is the size of the current loop it creates. The smaller the current loop, the lower the ESL. The IDC architecture shrinks the distance between terminations to minimize the current loop size, further reducing inductance by creating adjacent opposing current loops.
“The equivalent series inductance (ESL) of a single capacitor or an array of capacitors in parallel determines the response time of a power delivery network (PDN). The lower the ESL of a PDN, the faster the response time. A designer can use many standard MLCCs in parallel to reduce ESL or a single low ESL inter-digitated capacitor device,” said Tim Piver.
Featuring a footprint of 1.6mm x 0.80mm, the IDC Series is available in Pb-free and SN/Pb terminations for military applications.
