comes down to a battle for board space. As consumer wearables, IoT devices, and high-performance computing modules pack more features into smaller enclosures, printed circuit board (PCB) real estate has become an incredibly valuable commodity. Moving away from legacy through-hole parts and bulkier surface-mount devices (SMDs) is no longer optional\u2014it is a baseline requirement for modern layouts. At the center of this shift is the 0402 SMD resistor. It represents the sweet spot between space efficiency and manufacturing yield, making it the go-to choice for modern digital and analog circuits. Whether you are routing a high-speed digital bus, cleaning up an RF front-end, or moving a prototype [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_seopress_titles_title":"","_seopress_titles_desc":"","_seopress_robots_index":"","_seopress_robots_follow":"","_seopress_robots_imageindex":"","_seopress_robots_snippet":"","_seopress_robots_primary_cat":"","_seopress_robots_breadcrumbs":"","_seopress_robots_freeze_modified_date":"","_seopress_robots_custom_modified_date":"","_seopress_robots_canonical":"","_seopress_social_fb_title":"","_seopress_social_fb_desc":"","_seopress_social_fb_img":"","_seopress_social_fb_img_attachment_id":0,"_seopress_social_fb_img_width":0,"_seopress_social_fb_img_height":0,"_seopress_social_twitter_title":"","_seopress_social_twitter_desc":"","_seopress_social_twitter_img":"","_seopress_social_twitter_img_attachment_id":0,"_seopress_social_twitter_img_width":0,"_seopress_social_twitter_img_height":0,"_seopress_redirections_value":"","_seopress_redirections_enabled":"","_seopress_redirections_enabled_regex":"","_seopress_redirections_logged_status":"","_seopress_redirections_param":"","_seopress_redirections_type":0,"_seopress_analysis_target_kw":"","_seopress_news_disabled":"","_seopress_video_disabled":"","_seopress_video":[],"_seopress_pro_schemas_manual":[],"_seopress_pro_rich_snippets_disable_all":"","_seopress_pro_rich_snippets_disable":[],"_seopress_pro_schemas":[],"footnotes":""},"categories":[14],"tags":[],"class_list":["post-9533","post","type-post","status-publish","format-standard","hentry","category-electronic-circuit"],"acf":[],"meta_box":[],"_links":{"self":[{"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/posts\/9533","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/comments?post=9533"}],"version-history":[{"count":0,"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/posts\/9533\/revisions"}],"wp:attachment":[{"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/media?parent=9533"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/categories?post=9533"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lead-pcb.com\/ja\/wp-json\/wp\/v2\/tags?post=9533"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
